Patented June 24, 1930 l Parser carries ELMER Liann, oF LEXINGTON, NnBra/.lismiv SANITARY ICLESS SHPPNG- CONTAINER Application filed Jun-e 26, 1928. Serial No. 288,446.

This invention relates in general to insulated containers and 1n particular to an insulating structure. The primary purpose of f the invention 1s to provide a container with insulated walls of the least possible thickness that will edectually prevent the transfer of heat through the insulation tor or from the container'so insulated, over a long period of time.

The invention is adapted for use for containers of a wide range of products, such as ice cream, milk, hot liquids, and the like, but is described hereiny in one particular form as shown by the accompanying drawing, in which- F ig. 1 is a side elevation of a container a plurality of sheets of heavypaper 12, here` shown as two in number.

A plate of wood 13 is placed against the bottom of the container to extend outwardly around therefrom to the outer sheet of paper 12, and the sheets of paper 12 and veneer 11 are held in place by the top hoop 14;, the .intermediate hoop 15 and the bottom hoop 1G, the hoop 1G being secured by nails (not shown) to the plate 13.

The three hoops are preferably made of wood and in addition to their retaining usage serve as means to receive circumferentially therearound and to space a sheet of wood veneer 17 from the paper 12. The space between the paper 12and veneer 17 as determined by the hoops is filled with felt 18, and the outer surface of the veneer 17 is wrapped with several layers of paper 19, here shown as two in number.

Under the plate 13 is placed a plurality of sheets of paper 20, here shown las two in number, to extendl outwardly therefrom` to the outer sideof the paper 19, and a disc of leather 21 is placed under the paper 20 and has an upturned flange 22, to which is attached the canvas covering 23 which entirely surrounds the paper 19. 'At the top of the container, an annular channel meinber 24 is positioned to 'cover the ends cf the various wood and paper layers and is secured in place by the downturned legs 25 and 26 which compressively engage against the container 10 and canvas 23 respectively. The member 2li is made of metal and prevents the entrance of moisture between the layers of veneer and paper.

A'lid or cap is provided with an outer inverted cup-shaped leather shell 28, which is lined internally with aplurality of layers of paper 29, here shown as-two in number,

and against the paper 29 is placed aL disc of wood 30 around the `edge of which is secured a downwardly extending ring of metal 31. A layer of felt 32 is then placed against the disc 30 and ring 31 with a final undercovering of canvas 33, the felt 32 preferably beingl rubber coated against the canvas 33. The lid lits down with the canvas lining 33 contacting thereon and is retained on the container by the straps a3 which are secured to the lid and pass through buckles 34' carried on the straps 35 secured to the canvas 23. These straps by their angle of inclination from'the side wall to the out-er circumferential side of the lid form convenient handles for lifting the container. Y

lWhile I have here described my invention in one particular form, itis obvious'that structural changes may be made without departing from the spirit of the invention, and I, therefore, do not desire to be limited to the precise form as shown and described nor any more than may be required by the following claims.

I claim:

1. A container comprising an inner receptacle, layers of insulating material therearound, said layers being comprised of materials of porosity diiferent one from the other, and a ring at the top of the receptacle covering the ends of and securing said material to the receptacle, and a cover adapted to be resiliently littcd over and around the outside of said 1ing, -said cover being formed in the shape of an inverted cup and comprising a rigid core, a resilient covering on the underside of the core, an annular' band ixed to and depending iirom said core, and layers of nonconducting material on both sides of said band, the total combined horizontal thickness of said material and band being suficient to space the outer annular face of said cover ata substantial distance from the Vertical Wall of said container.

2. A container comprising an inner receptacle, layers or" insulating material therearound, said layers being comprised of materials of porosity diierent one from the other, and a ring at the top or" the receptacle covering the ends of and securing said 1naterial to the receptacle, and a cover adapted to be resiliently fitted over and around the outside of said ring,rsaid cover being formed in the shape of an inverted cup and comprising a rigid core, a resilient covering on the underside of the core, an annular band iied toand depending tromsaid core, and layers ot non-conducting material on both sides of said band, the total combined horizontal thickness of said material and band being suthcient to space the outer annular faceV of said cover at a substantial distance from `the vertical Wall of said container, the outer of said layers being made of a yieldingmaterial, and a pair oi straps detacliably eX- tending obliquely upwardly from said outer layer to be attached to the outer annular Wall of said cover as a means of compressively securing said cover yieldingly on said container and forming handles thereby.

In a container, an inner receptacle, insulating material lined around he receptacle, a yielding Wrapper around said material, a cover having an annular depending Wall of appreciable thickness therearound adapted to iit around the outside of said Wrapper, a pair or" spaced apart adjustable straps extending obliquely 'from points on said Wrapper spaced substantially below said cover and upwardly to the outer side of said annular Wall whereby said cover may be secured compressively over said receptacle and handles are formed by said straps.

In testimony whereof I aiiiX my signature.

ELMER LENE.
